ipython bug with file token.py in path

I am not able to replicate this problem as described. Would you please see if you can replicate it now and provide a more complet step by step process.

The version of Python you are running is not the one provided by any current Ubuntu release. What Python are you running?

$ apt-cache policy ipython python-minimal
ipython:
  Installed: 0.7.3-1
  Candidate: 0.7.3-1
  Version table:
 *** 0.7.3-1 0
        500 http://archive.ubuntu.com feisty/universe Packages
        100 /var/lib/dpkg/status
python-minimal:
  Installed: 2.5.1-0ubuntu3
  Candidate: 2.5.1-0ubuntu3
  Version table:
 *** 2.5.1-0ubuntu3 0
        500 http://archive.ubuntu.com feisty-proposed/main Packages
        100 /var/lib/dpkg/status
     2.5.1~rc1-0ubuntu3 0
        500 http://archive.ubuntu.com feisty/main Packages

But in Debian Etch with python2.4 occurs the same problem. The problem is with ipython!

Step by step:

1. install packages ipython
2. run ipython (works fine)
3. create token.py file in a directory in PYTHONPATH
4. run ipython (error!)

. . . . . . . . .

$ sudo aptitude install ipython [ok]
$ ipython [ok]
$ touch token.py [ok]
$ ipython [NameError: name 'N_TOKENS' is not defined]
$ rm token.{py,pyc}
$ ipython [ok]

Thanks!

Where are you putting the token.py file that you made? I'm still unable to replicate this when I put it in /usr/local/lib/python2.5/site-packages (which is in the PYTHONPATH).

BTW, I did upgrade to the unreleased Python you are running too in an attempt to replicate it. Still no luck.

What architecture are you running?

Hmm

The token.py must be first than /usr/lib/python2.5/token.py.

Try:

$ PYTHONPATH=/usr/local/lib/python2.5/site-packages:$PYTHONPATH ipython

or put him in the same dir that you run ipython!

Thanks!

/usr/lib/python2.5/token.py did it. Confirmed.

Creating a module with the same name as a built-in one will give you problems of you put it as first in your $PATH. This should not be considered a bug as this is expected python behaviour.
